NON-FILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 551,845, dated December 24, 1895.

Application filed March 2, 1895.

To all whom it may concern.-

Be it known that I, BERNARD H. BERKMAN, a citizen of the United States, and a resident of New York, county of New York, and State of New York, have invented certain new and useful Improvements in Non-Fillable Bottles, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which similar figures of reference indicate corresponding parts in all the figures.

My invention relates to non-fillable bottles, and the object thereof is to produce a stopper so constructed that when the bottle has been once filled and the stopper applied the bottle may be emptied of its contents, but cannot be refilled, whereby I guard against frauds often practiced on the proprietors of certain forms or kinds of liquors, cordials, medicines, &c., which are usually bottled by the proprietors, and which bear their distinctive marks, by parties so inclined, simply by re filling the empty bottles with an article of their own make or with an article of the same general class as that originally contained, but of a cheap or worthless variety, and selling the same as the original article. This object I accomplish by means of the construction set forth in the following specification, of which the accompanying drawings form a part, in which- Figure 1 represents a central vertical section of the neck of the bottle provided with my improvement; Fig. 2, a section on the line :1: a: of Fig. 1; and Fig. 3, a view similar to that shown in Fig. 1, the bottle being held in the position necessary to discharge its contents.

Referring to the drawings, the numeral 2 designates the neck of a bottle provided with my improved stopper, which is constructed as follows: A tubular casing 3, designed to fit closely the neck of the bottle, is provided with an upper tubular extension 4 of less diameter than the main body of the casing 3, these parts being connected by a horizontal flange or plate 5 formed integral therewith. NVithin the upper tubular portion 4 is placed a short tube 6, the upper end of which is closed by a hinged valve 7, convex on its lower side in order to give it weight. The upper end of the tubular portion 4 is again con- Serial No. 540,272. lNo model.)

tracted, forming an upper smaller tube 8, screw-threaded on its outer surface, to which. is applied a screw-threaded cap 9, and extending downwardly from the small tube 8 is a perforated tube 10, which forms an annular chamber 11 between said tube 10 and the upper end of the tube 4.

The tubes 3, a and 8 may all be formed from one piece of metal, if desired, and the tube 10 may be secured to the tube 8 in any preferred manner, as may also the tube 6.

The neck 2 of the bottle is provided with an annular groove and projection. 12, and in assembling the parts the lower end or casing 3 of the stopper is forced down over this groove andcorrugation, and a lathe or swaging device is then applied and the metal of the casing forced into the groove and caused to assume the form of the groove and corrugation in the bottle-neck, as shown at 13. This forms a secure attachment for the stopper, and one which will prevent its removal without the destruction of the bottle.

Before applying the casing of the stopper to the neck of the bottle, as above described, the interior thereof may be covered with some form of cement in a plastic condition, and this will, when the cement becomes set, add to the security of the connection between the bottle neck and stopper and make the same perfectly safe and tight.

The operation is as follows: The bottle be ing filled and the stopper applied as described, the contents of the bottle may be poured out in the usual manner by removing the cover 9 and holding the bottle in the usual position, the valve '7, under the influence of the fluidpressure thereon, opening to the position shown in Fig. 3, when the contents will flow out around said valve and through the perforations in the tube 10, and this operation may be repeated or continued till the contents of the bottle are exhausted. The position and arrangement of the valve 7, however, is such tle will be effectually prohibited, and it will be readily seen that the operation or the valve 7 will be the same in any position in which the bottle can be held in the operation of filling the same, or in any attempt to do so.

The perforated tube 10, in addition to limiting the movement of the valve 7, also prevents the insertion of a Wire or other article for the purpose of preventing the seating of the valve in an attempt to fill the bottle.

It will thus be seen that I accomplish the object of my invention by a device simple in construction and operation, and one which is easily applied to a bottle and not likely to get out of order, and which does not add mate rially to the cost.

Having thus described my invention, What I claim, and desire to secure by Letters Patcut, is-- A bottle stopper comprising a tubular casing 3 adapted to be secured on the neck of a bottle and having an upward extension 4 of less diameter than the mouth of the bottle,

and a horizontal plate 5 connecting said. extension and casing and arranged to rest upon the mouth of the bottle, a tube (3 fitted in the lower end of said extension, a valve 7 pivoted to said tube and adapted to be seated thereon, a tube 8 of less diameter than the extension, a perforated tube 10, projecting from said tube 8 into the extension and adapted to limit the upward movement of the valve, and a cap 9 arranged on the tube 8, substantially as described.

I11 testimony that I claim the foregoing as my invention I have signed my name, in presence of two Witnesses, this 27th day of February, 1895.
